John,

If possible, can you post a picture of either the old or new part that they're describing as a "vibration dampener"? I currently have the driveshaft removed from my 86 300E, and the only rubber parts on it are the flex disks at each end and the center support bearing rubber mount in the middle, which is bolted to the chassis. There's no part I can see on mine that, even if it came loose, would be able to traverse the driveshaft. Is this something that's common on MB's other than the 300E, or perhaps peculiar to the 190D or the manual trans model in particular? If you can quote a part number, that would great as well. That way I could ask to see one at the dealer's parts department.

Always eager to learn something new...

Gary
